Fetal interhemispheric cyst

Dr Owen Kang and Radswiki et al.

A fetal interhemispheric cyst refers to an interhemishperic cyst diagnosed in utero. It is seen as a cystic collection located in the interhemispheric fissure, with or without communication with the ventricular system.


Considerations include:

  • midline fetal arachnoid cyst: no associated agenesis of the corpus callosum
  • cyst-like lesions related to physiologic median structures
    • enlargement of the cavum septi pellucidi 2
    • enlargement of the cavum vergae 2
